Frequently Asked Questions

QUEENSMTP.COM is a professional email delivery platform providing SMTP services, bulk email delivery, transactional email, and email API for businesses of all sizes. We help companies send emails reliably with high deliverability rates.

SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails. An SMTP service like QUEENSMTP.COM provides managed, optimized email sending infrastructure so you do not have to run your own mail server. This ensures better deliverability, reliability, and scalability.

QUEENSMTP.COM offers competitive pricing starting at $9/month, dedicated IPs on all paid plans, 99.9% uptime guarantee, real-time analytics, and expert email deliverability support. We focus on simplicity and performance.

We support SPF, DKIM, and DMARC email authentication protocols. All are included in every plan and we provide step-by-step setup guides with DNS record generators. See our SPF, DKIM & DMARC setup guide for detailed instructions.

Yes, but we recommend using separate sending domains or subdomains for marketing and transactional emails. This protects your transactional email reputation from potential marketing email issues.

Email deliverability is the ability to reach recipients inboxes rather than spam folders. QUEENSMTP.COM ensures high deliverability through dedicated IPs, authentication setup, content analysis, reputation monitoring, and automatic suppression of invalid addresses. Read our email deliverability guide for best practices.

Integration is simple: sign up, get your SMTP credentials or API key, and configure your application to send through our servers. We support SMTP relay, REST API, and official SDKs for all major programming languages.

Yes, we provide automatic IP warming for new dedicated IPs. Our system gradually increases sending volume over 2-4 weeks to establish a positive sender reputation with ISPs.

QUEENSMTP.COM provides real-time analytics including delivery rates, open rates, click rates, bounce rates, spam complaint rates, and detailed per-recipient event logs. All data is accessible through the dashboard and API.

QUEENSMTP.COM is designed for permission-based email only. This includes emails to people who have opted in to receive your messages — marketing newsletters, transactional notifications, and account-related emails. We do not support unsolicited bulk email.

We offer a 30-day money-back guarantee on all plans. If you are not satisfied with our service within the first 30 days, contact us for a full refund.

Yes, we offer a library of responsive email templates and a drag-and-drop template editor. You can also upload your own HTML templates and use dynamic variables for personalization.

All plans include 24/7 email support. Professional and Enterprise plans also include priority support with faster response times, dedicated account managers, and phone support.

Yes, you can verify and send from multiple domains on any plan. Each domain can have its own authentication records and tracking settings.

QUEENSMTP.COM uses TLS encryption for all connections, supports SMTP over SSL (port 465) and STARTTLS (port 587), and stores all data in encrypted databases. We comply with SOC 2 and GDPR security requirements.

Most customers are sending emails within 15 minutes of signing up. Create an account, add your domain, configure DNS records using our step-by-step guide, and start sending. Our setup wizard walks you through every step.

A dedicated IP address is an IP used exclusively by your account for sending emails. It gives you full control over your sender reputation. Dedicated IPs are recommended for businesses sending more than 50,000 emails per month. QUEENSMTP.COM includes dedicated IPs on Professional and Enterprise plans.

QUEENSMTP.COM provides reputation monitoring tools in your dashboard showing bounce rates, complaint rates, and blacklist status. We also send automatic alerts if your reputation metrics fall below safe thresholds, so you can take corrective action immediately.

Email throttling is the practice of controlling sending speed to avoid overwhelming recipient mail servers. QUEENSMTP.COM automatically adjusts sending rates per ISP based on their known preferences and real-time feedback, maximizing delivery speed without triggering rate limits.

Yes, QUEENSMTP.COM integrates with all major e-commerce platforms. Use our SMTP settings in Shopify, install the WP Mail SMTP plugin for WooCommerce, or connect via our API for Magento. All transactional emails (orders, shipping, receipts) will be delivered reliably.

Your email logs and analytics data are retained for 30 days after cancellation, allowing you to export any needed reports. After 30 days, all data is permanently deleted from our servers in compliance with our privacy policy and GDPR requirements.

Yes, QUEENSMTP.COM supports internationalized domain names (IDN) and UTF-8 encoded email addresses. You can send to and from email addresses that use non-ASCII characters in both the local part and domain name.

High bounce rates signal to ISPs that you are sending to invalid addresses, which damages your sender reputation. QUEENSMTP.COM recommends keeping bounce rates below 2%. Our system automatically suppresses hard bounces and provides list cleaning recommendations to help you maintain healthy rates.

Enterprise plan customers can use custom tracking domains and branded email headers to white-label our infrastructure. This means your clients see your brand throughout the email delivery process, not ours. Contact sales for white-label pricing and setup details.

DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication policy that tells receiving servers what to do when SPF or DKIM checks fail. Setting up DMARC is strongly recommended and required by Gmail and Yahoo for bulk senders. See our DMARC setup guide.

Start by checking your authentication records (SPF, DKIM, DMARC) in our dashboard. Then review bounce logs for specific error messages. Common issues include missing DNS records, blacklisted IPs, and content triggering spam filters. Our support team can help diagnose complex deliverability problems.

Yes, QUEENSMTP.COM supports sending AMP (Accelerated Mobile Pages) emails alongside standard HTML and plain text versions. AMP emails allow interactive content like carousels, forms, and live data directly within the email client.

All plans include a 99.9% uptime SLA. Enterprise customers can negotiate custom SLAs with higher uptime guarantees, dedicated support channels, and guaranteed response times. SLA credits are issued automatically if uptime falls below the guaranteed threshold.

Yes, you can import contacts via CSV upload or connect through our API. If you are migrating from another provider like SendGrid, Mailgun, or Amazon SES, our support team can assist with the migration to ensure zero downtime and no data loss.

QUEENSMTP.COM prohibits spam, phishing, malware distribution, and any unsolicited bulk email. All sending must be permission-based with valid opt-in consent. We also prohibit content that promotes illegal activities, counterfeit goods, or deceptive practices.
